This Whole AC noise thing...SOLUTION!


I've been spending hours researching the whole issue of AC noise/distortion finding its way into our stereo systems......My conclusion is it is VERY real.    I've also concluded that any of the generally supported methods of removing it are at best ineffective and at worse nonsense.    There are simply WAY too many devices in our house and our neighbors houses that generated unwanted AC noise.....Through the power cables AND airborne.    Various power conditioners and better cables can mitigate the issue, but they can not totally eliminate it. And the older your houses wiring, the older the transformer on the pole outside and the older the wires coming into your house...The issues thatr your neighbors might have in their house...The worse the problem is.    But I think there is a solution.....Disconnect from the GRID entirely! In the last few years, the Lithium battery powered portable generator industry has been on a roll.....These devices have gotten bigger and better at far reduced price.    Basically what they are is a large Lithium battery and a well regulated DC to AC inverter all in one box...Not connected to anything but your stereo...You charge it with an AC charger when you are not listening to your system, and unplug the charger when you are listening...or, if you have the room, you charge it with a few solar panels.    If you are the DIY type you can buy a few LiFo cells, a BMS (battery management system) a good charger and a quality DC to AC inverter for around $2000....Loads of YouTube videos on this. Search Will Prowse on YT and plan on spending a few hours!    Be aware, this will not solve the RF noise issue from devices sending noise through the air to your cables....Short interconnect length, shielded AC cables and disconnecting as many wall warts, USB adapters and compact and LED lights will greatly help.    Comments?

Everyone always falling into the same trap of thinking there is "a" "solution".

Sometimes posting this crap PC at work means not having italics, bold, underline. But we still have the scare quotes. So we put scare quotes around "a" and "solution" hoping people will get it.   

Sorry to sound imperious, but that is what scare quotes are for. Not the usual quotes indicating something someone said. Scare quotes draw attention to the words as opposed to the speaker of the words.   

In a perfect world everyone would understand all that means is we are never done. There is never "a" solution but instead only what works for now. It is fun and exciting to find the new one that works better than the old one. Solutions are like Porsches: The best one will always be the next one.
